Description
General-Purpose Digital Input/Output 4, Clock. This is a multifunction pin. By default and after
power-on reset, this pin is configured as an input. The pin has an internal weak pull-up resistor.
This pin remains unconnected when not in use. This multifunction pin can be configured in
one of two states, namely
General-Purpose Digital I/O 4.
Output a 2.56 MHz clock.
Nominal 2.6 V Output from On-Chip Regulator.
Crystal Oscillator Output. If an external crystal is not used, this pin is left unconnected.
Crystal Oscillator Input. If an external crystal is not used, connect this pin to the DGND system
ground.
High Voltage Wake-Up Pin. This high voltage I/O pin has an internal 10 kΩ pull-down resistor
and a high-side driver to VDD. If this pin is not used, do not externally connect it.
Battery Power Supply to On-Chip Regulator.
Ground Reference. This is the ground reference for the internal voltage regulators.
High Voltage Serial Test Interface Output Pin. If this pin is not used, externally connect it to the
IO_VSS ground reference.
Ground Reference for High Voltage I/O Pins.
LIN Serial Interface Input/Output Pin. This is a high voltage pin.
